Both Windows and Mac OS X have major updates that you pay for, and minor updates you don't pay for. You are trying to create a distinction where there is none.

Both Windows and Mac OS X have major updates that you pay for, and minor updates you don't pay for. You are trying to create a distinction where there is none. Mac OS X doesn't have "service packs", so I don't know how you can say they are "less frequent" -- they simply don't exist, as such. That's what I mean by semantics. You're talking FUD like a computer store sales drone.
